Jaguar XJ 4WD tackles the coldest town on earth (video)

Jaguar XJ 4WD (pictured) tackles the coldest town on earth If you’ve ever driven a Jaguar XJ in any amount of snow, you’ll know it’s pretty useless. You need a handy supply of snow socks and winter tyres too if you’re going to make any length of journey in seriously cold and snowy conditions without stopping to dig yourself out at regular intervals. But Jaguar now has an XJ that can tackle poor and snowy conditions in the AWD XJ (although, sadly, it’s not on sale in the UK) so they’ve headed out on a 2,000 mile round trip in temperatures down to -50 degrees to show that the 4WD XJ just keeps on going.

Alfa Romeo 4C Spider revealed: Geneva Motor Show

The Alfa Romeo 4C Spider (pictured) revealed in Geneva The Alfa Romeo 4C is the epitome of a modern ‘supercar’, with ultra light weight (for a production car) allowing the 4C to produce very good performance from its modest 17500cc engine. So producing an Spider convertible immediately raises the weight issue in a more dramatic way when the car’s abilities are so dependent on it low weight, but it seems the Alfa Romeo 4C Spider – previewed as a production car with a concept at Geneva today – has managed to keep the wight penalties of the convertible 4C down to a minimum. Thanks to a canvas roof and carbon fibre rollover bars, the weight penalty for the Spider is only about 60kg (around a 7 per cent gain) which shouldn’t hurt performance too much.
